The red-bodied grasshopper ( Omocestus haemorrhoidalis ) is a grasshopper from the family of field locusts (Acrididae).

features

It is named after the red color of the abdomen of the male. The males are relatively small, only about ten to 14 millimeters long, and are the smallest species in Germany within the genus Omocestus . The females are significantly larger and very difficult to distinguish from other Omocestus species. Typical is the singing of the males, a short ascending stanza of only two seconds, which sounds hasty and energetic and whose overtones are described as "scraping".

The females can easily be confused with Myrmeleotettix maculatus , the males with Stenobothrus stigmaticus .

Occurrence

The red-bodied grasshopper is a pointer species for local climates that are strongly influenced by heat. It lives in poor vegetation, sandy to stony ground, also often adjacent to grass. He is described in the literature as purely drought-loving. Typical sites are therefore open sites in heaths, quarries and dry grassland , inland dunes and gravel paths.

Adults can be seen from early July to October.

distribution

The red-bodied grasshopper is generally more common in the south of Germany. Extinct in Hamburg , it is considered critically endangered in Schleswig-Holstein and Rhineland-Palatinate , and endangered in Lower Saxony , Hesse and Baden-Württemberg . In Saxony, there is a decline in populations, particularly in the montane area. The species is currently not threatened in North Rhine-Westphalia and Bavaria . In Germany's Red List of Endangered Animals, the red-bodied grasshopper is named with status “G” (endangered, but status unknown).
